My backlog is continuously growing.. it's not the only patch-series I have pending for too long, I'm sincerely sorry. I'm working hard on getting all that stuff out, but note that I will not be able to get this ready before FOSDEM (in 2 weeks). So if you want to pick this up before 3rd of February, I would be more than glad about it. I will review any changes. Otherwise, you'd have to wait for at least 2 more weeks before I can send it out. Also feel free to extract any small part of the series if you don't feel confident about the other stuff. So you can just move the raw_request()/raw_report() into a separate patch. We *definitely* need this callback, so I'd be fine if we add it early.
